That sounds more like a Datura trip (deliriant) than a mushroom one. But this guy sounds like they got *smashed* by it, whatever happened...some fucked up ****. This is why drugs are not for everyone and psychedelics even more so...

Could of been Fly Agarics whic are a deliriant, they don't say the shrooms were psilocybes anywhere I can see.

I'm with Miyagi and Orlando on this one... this doesn't sound like mushrooms to me. Then again, anything can happen with someone who is already on the edge, and the trip could just push him off. Really, until toxicology tests are done, it's still up in the air. Those shrooms could have been doped with anything.

Psychotic episodes are well documented with psilocybin.
Teas and extracts make dosages more difficult to judge.
That said, friends from the area claim Amanita Muscaria was used in this case, i for one tend to see that as more likely.
